This is the first I've heard of cloudflared (aka Argo). It's a DNS over HTTPS proxy. As far as I know Firefox is working to get DNS over HTTPS into Nightly so it can be used directly in the browser, but this proxy allows your whole system to use DNS over HTTPS without having to change anything (other than pointing /etc/resolv.conf or equivalent at 127.0.0.1). Pretty cool!
